Hmm. Newer kernels use sdX devices for USB. maybe root=/dev/sda1 ?<br><br><div class="gmail_quote">2009/1/2 Courtney Thomas <span dir="ltr"><<a href="mailto:courtneycthomas@bellsouth.net">courtneycthomas@bellsouth.net</a>></span><br>

tryin' to boot an Isolinux.iso, huh ?</div>
<div><br></div>Framebuffer is a low-level video thing that writes video bits
to video ram and to the graphics chip. You may need to try some
different video= lines. I don't know isolinux details so you'll have to dig on
their site for specific settings. But I'll bet that something like video=vga
may get you a working screen.<br><br>You will need the framebuffer stuff
compiled into the kernel to use it.<br><br>AH! You need to spec framebuffer
mode like 788, etc. Knoppix has good details on this.<br><br>Found this on <a href="http://www.linuxsir.org/bbs/archive/index.php/t-168922.html" target="_blank">http://www.linuxsir.org/bbs/archive/index.php/t-168922.html</a>:<br>
<br>My
isolinux.cfg looks like this:<br><br>timeout 30<br>prompt 1<br>display
menu.txt<br>default 1<br>label 1<br>kernel vmlinuz<br>append
initrd=initrd.gz<br><br>label 2<br>kernel vmlinuz<br>append initrd=initrd.gz
vga=788<br><br>label 3<br>kernel vmlinuz<br>append initrd=initrd.gz
vga=791<br><br>menu.txt is a simple text file that looks like:<br><br>1) Text
Mode<br>2) 800x600 x 16bit colour<br>3) 1024x768 x 16bit colour<br><br>The
user just enters '1' if they want text mode, 2 for 800x600 and so on.<br><br>
